Re: What is your favorite headlight bulb?

I have the 03 with HID low beams. I replaced my high beam lamps with Sylvania Silverstar bulbs and found them to be much whiter and brighter than stock lamps. I imagine I'll replace the fog lamps with Silverstar when the need arises.....I just don't use them much so I'm in no big hurry.

Re: What is your favorite headlight bulb?

I'm pretty convinced after reading tons of posts on various forums to purchase SylverStars for my 93 Seville (I know... it's not an Escalade but this thread was helpful and I believe might be able to answer my question).

So, I was looking at the SilverStar regulars and the SilverStar Ultras on several sites, including the Sylvania site. The ONLY difference I could find are the color temperature on the Ultras is 4100 but it's 4000 on the regulars, yet they're roughly $5 per bulb different in price. I also noticed Sylvania's claim that the regular SylverStars offer 30% betting overall lighting than stock but the Ultras offer 50% more lighting. I find this claim to be hard to believe!

Is 100 higher in color temp actually going produce 20% light and vision than the regular SylverStar bulbs? I'm just confused as to what makes the Ultras that much better than the regular SylverStar bulbs if the only difference is 4100 instead of 4000 in color temperature.

I hope someone can help me understand this. I'm willing to pay $5 more per bulb, but ONLY if there is going to be a huge, noticeable difference.

Thanks much! And sorry to invade your Escalade thread. (Besides, this post might get this thread back alive since it's been close to 5 years since anyone posted in this thread).

Re: What is your favorite headlight bulb?

The difference in temperature between 4000k to 4100k will result in a negligible difference in light output. Sylvania produces a good product in the Silverstar bulb, but their claim of an additional 20% light output is exaggerated.
